Out of jail and free on bond, the group played the next night at the Warehouse, and two nights later, in a remarkable show of solidarity, The Dead, Fleetwood Mac and The Flock donated their income from that show to a bust fund. The Warehouse was surrounded by police all three nights, but that didn't stop some fearless and reckless insider from dispensing a large amount of LSD to the crowds on hand and, in the words of Rolling Stone, "the bands blew the lid off the house." A few weeks later, Bill Graham put on a bust benefit show at Winterland featuring the Airplane (who had been busted at the same New Orleans hotel a couple of weeks before the Dead), Quicksilver, Santana and It's A Beautiful Day. After expenses, the show raised $15,000, which was enough to cover the initial legal expenses after the bust.
